payload envelopes are identified by the OTSPE signal being set high. The OTV5
signal pulses high to mark the V5 bytes of each outgoing tributaries.
Figure 15
The three tributary payload processor may be individually disabled. Incoming
data destined to a disabled processor is re-transmitted unchanged to the
outgoing data after some delay. The amount of delay is dependent on the
relative phase of the incoming frame pulse (IC1J1) and the outgoing frame pulse
(OC1J1). Figure 16 shows the delay for the three possible alignments of IC1J1
in relation to OC1J1. The delay from the rising edge of SCLK where TUPP
samples DIN[7:0] to the rising edge of SCLK where a downstream device
samples DOUT[7:0] is 5, 6, or 7 cycles.
